Fill a pot with 3 inches of water, or just enough to submerge the silverware completely. Add 1 tbsp. salt and 1 tbsp. baking soda to the water. Put the pot on the stove at high heat and bring it to a boil.
Drop a sheet of aluminum foil in the boiling water. The sheet must be close to the same size as the bottom of the pot.
Lower the silverware into the boiling water with a pair of tongs. Each piece of silverware must come in contact with the aluminum foil or another piece of silver.
Remove the pot from the heat and allow the silverware to soak for 10 minutes.
Remove the silverware from the water and wash, rinse and dry them.
